Variability of the Sun's Luminosity Places Constraints on the Thermal Equilibrium of the Convection Zone
Dudok de Wit, T.; Vieira, L. E. A.; Kopp, G. +5 more
Luminosity, which is the total amount of radiant energy emitted by an object, is one of the most critical quantities in astrophysics for characterizing stars. Equally important is the temporal evolution of a star's luminosity because of its intimate connection with the stellar energy budget, large-scale convective motion, and heat storage in the s…
MUSUBI (MegaCam Ultra-deep Survey: u*-band Imaging) Data for the COSMOS and SXDS Fields
Ouchi, Masami; Shimasaku, Kazuhiro; Ohyama, Youichi +11 more
The Subaru Hyper Suprime-Cam (HSC) Strategic Survey is the latest-generation multiband optical imaging survey for galaxy evolution and structure formation. The "Ultra-deep" component of the HSC survey provides grizy broadband images over ~3.4 deg2 to detection limits of ~26-28 AB, along with narrowband images, in the COSMOS and SXDS fie…
The Diffuse X-Ray Background of the Insight-HXMT/LE Telescope in the Galactic Plane
Zhang, Shu; Zhang, Shuang-Nan; Liu, Yuan +11 more
Accurately estimating of diffuse X-ray background (DXB) is essential for the investigation of sources in the Galactic plane observed with Insight-HXMT/LE, which is a collimated telescope in the soft X-ray energy band with a relatively large field of view. In the high-Galactic-latitude region, DXB is dominated by the cosmic X-ray background, which …
Dippers from TESS Full-frame Images. II. Spectroscopic Characterization of Four Young Dippers
Takita, Satoshi; Hattori, Kohei; Muto, Takayuki +9 more
Photometric monitoring by the Transiting Exoplanet Survey Satellite (TESS) has discovered not only periodic signals by transiting exoplanets but also episodic or quasiperiodic dimming around young stellar objects. The dimming mechanisms of these objects, the so-called "dippers," are thought to be related to either the accretion property or the str…
PHANGS-ALMA: Arcsecond CO(2-1) Imaging of Nearby Star-forming Galaxies
Sandstrom, Karin M.; Bolatto, Alberto D.; Henshaw, Jonathan D. +69 more
We present PHANGS-ALMA, the first survey to map CO J = 2 → 1 line emission at ~1″ ~100 pc spatial resolution from a representative sample of 90 nearby (d ≲ 20 Mpc) galaxies that lie on or near the z = 0 "main sequence" of star-forming galaxies. CO line emission traces the bulk distribution of molecular gas, which is the cold, star-forming phase of…
The TESS Objects of Interest Catalog from the TESS Prime Mission
Jayaraman, Rahul; Pál, András; Torres, Guillermo +102 more
We present 2241 exoplanet candidates identified with data from the Transiting Exoplanet Survey Satellite (TESS) during its 2 yr Prime Mission. We list these candidates in the TESS Objects of Interest (TOI) Catalog, which includes both new planet candidates found by TESS and previously known planets recovered by TESS observations. We describe the p…
The Dark Energy Survey Data Release 2
Bacon, D.; Bechtol, K.; Juneau, S. +135 more
We present the second public data release of the Dark Energy Survey, DES DR2, based on optical/near-infrared imaging by the Dark Energy Camera mounted on the 4 m Blanco telescope at Cerro Tololo Inter-American Observatory in Chile. DES DR2 consists of reduced single-epoch and coadded images, a source catalog derived from coadded images, and associ…
The Hipparcos-Gaia Catalog of Accelerations: Gaia EDR3 Edition
Brandt, Timothy D.
We present a cross-calibration of Hipparcos and Gaia EDR3 intended to identify astrometrically accelerating stars and to fit orbits to stars with faint, massive companions. The resulting catalog, the EDR3 edition of the Hipparcos-Gaia Catalog of Accelerations (HGCA), provides three proper motions with calibrated uncertainties on the EDR3 reference…
The California Legacy Survey. I. A Catalog of 178 Planets from Precision Radial Velocity Monitoring of 719 Nearby Stars over Three Decades
Henry, Gregory W.; Knutson, Heather A.; Kane, Stephen R. +20 more
We present a high-precision radial velocity (RV) survey of 719 FGKM stars, which host 164 known exoplanets and 14 newly discovered or revised exoplanets and substellar companions. This catalog updated the orbital parameters of known exoplanets and long-period candidates, some of which have decades-longer observational baselines than they did upon …
The CatWISE2020 Catalog
Teplitz, Harry I.; Schlegel, David J.; Mobasher, Bahram +20 more
The CatWISE2020 Catalog consists of 1,890,715,640 sources over the entire sky selected from Wide-field Infrared Survey Explorer (WISE) and NEOWISE survey data at 3.4 and 4.6 µm (W1 and W2) collected from 2010 January 7 to 2018 December 13. This data set adds two years to that used for the CatWISE Preliminary Catalog, bringing the total to si…
